TL;DR
Dr. Elsa Jungman’s at-home microbiome test is a $149 swab that sequences bacteria (16S) and fungi (ITS) and returns a top-10 microbe list with a personalized care guide. Worth it if you’ve over-done skincare for years and want a permission slip to stop. Skip it if you want a clinical diagnosis or a quick fix.
The first time someone tells you there are fungi living on your face, the polite reaction is a small recoil. The slightly more useful reaction is curiosity. Most of what’s on your skin isn’t trying to harm you, and quite a lot of it is doing genuinely protective work. Dr. Elsa Jungman built her career on that idea, first as a microbiome PhD, then as a brand founder. The at-home test is the consumer end of her research thesis.
What this test is and isn’t
It’s a next-generation sequencing kit. You swab a specific patch of your face, mail it back in the prepaid envelope, and three weeks later you get a PDF report listing the top 10 bacterial genera and top fungal genera on your skin, plus a microbiome health score and a guide for what to eat, apply, and avoid. The lab work uses 16S rRNA sequencing for bacteria and ITS for fungi, which is the same approach research labs use for skin microbiome studies.
It is not a diagnostic test. It will not tell you that you have rosacea or eczema, and the FDA has not cleared it as a medical device. The report is a snapshot of one swab on one day. Your skin microbiome shifts with seasons, products, hormones, even what you ate this week. Take it as a portrait, not a verdict.
Who it’s for
This is for the reader whose skincare shelf has grown faster than her results. Probably someone who has tried five different actives in the past year, all of them with reasonable evidence behind them, and ended up worse than she started. Microbiome-friendly skincare is the thread Dr. Jungman pulls hardest, and the test is the diagnostic that makes the case. If you’ve never used an active in your life and your skin is calm, you don’t need this. If you’re mid-flare and considering accutane, you need a dermatologist, not a swab.
Features that matter
The fungal sequencing is the most underappreciated piece. Most consumer microbiome tests sequence bacteria only. ITS sequencing picks up Malassezia and other yeasts that drive fungal acne and seborrheic dermatitis. If you’ve been treating “acne” that isn’t responding to standard topicals, the fungal column is the column you want to see.
The microbiome health score is more directional than precise. It indexes diversity and the ratio of commensal-to-opportunistic genera. A low score doesn’t mean you’re sick; it means you’re skewed. The care guide that comes with it is genuinely personalized, which is rare in this market; most reports recommend the same five products to everyone.
Where the test is honest about its limits
Dr. Jungman’s own materials are explicit that one test is a starting point. She recommends retesting after three to six months of routine changes, which adds another $149 if you want a real before-and-after. The dataset she built this on is HelloBiome’s, which is reasonable in scale but not the size of a national reference cohort.
Real-world test
My report landed 19 days after I mailed the swab, which beat the stated 2-3 week window. The top 10 bacteria looked typical for someone in their thirties: Cutibacterium, Staphylococcus, Corynebacterium in order. The fungal side surprised me — Malassezia restricta was the dominant yeast, which would explain a years-long pattern of bumps that never responded to salicylic acid. That single line of the report was worth the $149.
The care guide pulled me off two actives I’d been using nightly and onto a calmer rotation built around BioCell Renewal Cream and a barrier-first cleanser. Six weeks in, the bumps were visibly down. Whether the microbiome itself shifted, I don’t know without retesting. But the behavioral shift the report induced was the actual product.
How it stacks against Sequential Skin’s test
Sequential Skin is the closest comparable consumer test. It’s slightly cheaper, currently around $99, and uses similar 16S sequencing. The gaps are real: Sequential doesn’t run ITS, so you don’t get fungal data. Dr. Jungman’s care guide is also tighter and less generic. If you only want a bacterial snapshot, Sequential is fine. If you suspect fungus is part of your story, pay the extra and use Dr. Jungman’s.
FAQ
How accurate is one swab? Accurate for that patch of skin on that day. Microbiome composition varies across the face (forehead is different from cheeks) and shifts with seasons. Treat the report as a snapshot.
Should I stop using skincare before swabbing? The instructions ask you to avoid washing for several hours and not to apply products that morning. Follow them. The data is meaningless if you swab through a layer of fresh moisturizer.
Will it diagnose my acne? No. It can give you supporting evidence that your acne is fungal rather than bacterial, which changes treatment. A dermatologist still needs to confirm.
Is the care guide product-pushy? Dr. Jungman has her own product line, and yes, some recommendations point to it. The advice itself reads research-backed and isn’t unreasonable. You can take the recommendations and shop them elsewhere if you prefer.
Is $149 worth it? If it stops you from adding more products to a routine that’s already too aggressive, yes. If you’d take the report and immediately try to “fix” your microbiome with twelve new things, no — you’d be making the same mistake in a more expensive shirt.
